QSFP+ LR4 40G LC CISCO Compatible

ZKTel's QSFP+ (Quad Small Form-factor Pluggable Plus) is a new Multi-Source Agreement (MSA) for high speed application, such as 40Gbps, which provide four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gbps and supports a total of 40Gbps. The 40Gbps QSFP+ transceiver is well suited for Infiniband and 40GBASE-SR4/40GBASE-LR4 applications. It combines the higher density attractions of parallel modules with some of the key advantages normally associated with SFP+ based modules. It is intended for use short reach applications in switches, routers and data center equipment where it provides higher density and lower cost when compared with standard SFP+ modules.

QSFP SR4/QSFP+ SR4 It is designed to operate over multimode fibre systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 8 or 12 fibre MTP(MPO) connector.
        
QSFP LR4/QSFP+ LR4  It is designed to operate over single mode fibre system using four 10Gbps CWDM channel in 1300 band. Which is based on two LC connectors for optical connectivity and supports 40Gbps data rate links of up to 10km.
